Merge k sorted array

#1

Can you explain this line from the code
-> pq.push({arr[i][0],{i,0}})

#2

Let’s bifurcate it:
We are making pair of { i , 0 } let’s call it -> a
arr[i][0] , let’s call it -> b
Now you will see {b,a} which means we are making pair of b & a and then pushing it in priority queue
So, it means making pair of i & 0 and after that making pair it with arr[i][0] and then pushing it in priority queue.
